Reads an integer setting.

Syntax

Parameters

options_handle

name

The name of the option to read.

Return value

Sample

void print_starting_MFT( void )
{
   uint64_t options = truxton_options_create();

   int64_t mft = truxton_options_get_integer( options, "startatmft" );

   printf( "Will start processing the NTFS volume beginning at MFT %" PRId64 "\n" );

   truxton_options_destroy( options );
}

The PRId64 in the sample code above is a standard way of formatting a 64-bit signed integer in C. Over the years, different compilers on different operating systems used different format specifiers for things, these PRI macros, along with some tricky string concatenation the compilers perform for you, allow you to maintain a single code base without a bunch of macro magic.
